Definitions

  • the present invention relates generally to the field of telecommunications. More specifically, the present invention is directed to an improved telecommunications system that provides enhanced compatibility among the systems.
  • the hardware platforms of these systems essentially differ on the basis of their structural format, the nature of the backplane wiring and on the basis of the format. For example, this may be the dimensions of the peripheral assemblies. This leads to the fact that, due to these differences, an assembly developed for specific functions of, for example, a medium-sized or, respectively, large system in this series cannot be utilized in what is referred to as a smaller system. Due to the differences in the dimension, in the interfaces and in the mechanical plug-type connectors, they must be newly developed platform-related. This relates, for example, to specific performance features and specific office or, respectively data network accesses that, for example, are fundamentally present only for the more highly classified systems in the system series. This then leads to the fact that such specific solutions that are only provided for a limited number of such smaller systems can only be realized with a high cost.
  • One object of the invention is to overcome the above-mentioned shortcomings other objects and advantages of the present invention will become apparent from the following Summary and Detailed Description of the Preferred Embodiments.
  • One aspect of the invention is comprised therein that a small system is designed so that of its hardware platform can flexibly accept system-atypical, peripheral assemblies from a different system of the system series.
  • a corresponding, mechanical pre-performance only a slight adaptation measure is still required for such an acceptance of an assembly.
  • the resources for example, PCM-oriented or, respectively, HDLC-oriented plug-in locations of the assembly to be introduced as needed from another system are fundamentally already present.
  • this pre-performance for example within coupling path accesses, a certain compatibility is thus already present.
  • plug-in locations that have become free due to a system variation in the form of the use of more highly integrated structural units of a central assembly or those that are optionally provided from the very outset are employed as additional plug-in locations for peripheral plug-in assemblies.
  • Such plug-in assemblies of a higher system then serve the purpose of realizing a special service feature originally not available for the basic system.
  • the platform-specific development for such a service feature that is otherwise necessary is thus eliminated since a corresponding assembly can be employed for a plurality of platforms.
  • the additional plug-in locations are fashioned such in the view of the signaling supply that a few arbitrary plug-in assemblies from the repertoire of plug-in assemblies that are present in a system classified more highly within the system series can be additionally utilized in the sense of expanding the functionality of the system.
  • FIG. 1 illustrates a schematic block diagram of an embodiment of the system of the present invention.
  • This embodiment of the communication system for switching of connected communication terminal equipment to one another and for the connection of such terminal equipment to communication networks contains a central assembly ZB.
  • the system may connect public networks via corresponding office accesses.
  • a central assembly comprises, among other things, a controller ST comprised of a microprocessor, a memory and a clock.
  • the system also comprises a switching unit VE.
  • the latter is comprised, for example, of two periphery-oriented telecommunication modules ELIC 1 and ELIC 2 as well as of a coupling module MTSS (memory time switch).
  • the memory time switch MTSS respectively communicates with the periphery-oriented module ELIC via PCM-oriented interfaces, whereas communication of these components ELIC with the peripheral plug-in assemblies PB 1 through PBx ensues via ISDN-oriented, internal interfaces IOM 2 .
  • Such a periphery-oriented module ELIC is system-independently equipped, so that it also fundamentally offers the possibility of an HDLC (high data link control) signaling for communication with other modules.
  • FIG. 1 also indicates the system structure of a communication system that, for example, as what is referred to as a small system, forms the basic system of a system family.
  • This system family then also comprises “more highly” resonant systems within a predetermined sequence such as, for example, mid-sized and large systems. It can be provided for such a small communication system that, for example with respect to a minimum expansion level, periphery-oriented assemblies PBZ are also provided at the central assembly ZB. Further plug-in locations PB 1 through PBx for peripheral plug-in assemblies are then also present for a maximum expansion level.
  • plug-in locations or, respectively, the plug-in assemblies are system-specifically fashioned. They differ from the peripheral plug-in assemblies or, respectively, plug-in locations of a mid-sized and large system with respect to the dimensions, the interfaces and the mechanical plug-type connectors.
  • system-typically fashioned plug-in assemblies for specific functions already possible in the mid-sized and larger systems, this requires great expense.
  • all of the software required for this purpose would have to be introduced into the software of the central assembly ZB.
  • An example of such a desired expansion in the functionality is, for example, the possibility of being able to telephone via a mobile part upon incorporation of such a small communication system.
  • the assembly for CMI (cordless maticell integration) present for mid-sized and large systems would thus have to be system-specifically developed for this small system. For example, this would require the necessary printed circuit board format and, thus, specific layout and the required software.
  • Other examples are specific solutions for office accesses as required for certain countries and a plug-in card that enables the involvement into a local area network environment.
  • the expansion of the functionality for a small communication system could also be comprised therein that subscriber assemblies will be required with an increase plurality of subscriber connections per assembly.
  • individual assemblies among these system-typical assemblies also require the PCM connection in addition to the IOM 2 access. Further, some of these assemblies are connected to the controller via the microprocessor bus MP. For example, assembly identifiers and information that relate to connection data from an ISDN connection are communicated thereover.
  • the plug-in location SP for a plug-in assembly from a different system of the system series also exhibits a higher plurality of periphery ports as system-atypical plug-in location for periphery plug-in assemblies compared to the system-typical plug-in locations, PB 1 through PBx.
  • plug-in assemblies cover specific functions as needed and comprise a separate controller STE due to their underlying complexity, since they originally belong to a multi-processor communication system. Given their inventive transfer into a basic system, i.e. into a small communication system, this provides the advantage that they need not be completely integrated since they already bring a majority of the functions along with them. Only a slight adaptation still has to be undertaken. The critical software part for such an assembly fundamentally runs on this assembly itself. The access to the switching unit VE ensues via a PCM connection that has already been pre-performed, via which the switching of the B-channels is undertaken.
